I would like to nominate the snowflake who basically shut down a fastfood drive through this morning. The drive through lane is pretty narrow anyway due to the placement of a fence and the menu sign. And despite the fact that there are no parking spots anywhere next to the drive through lane, someone took it upon themselves to park perpendicular to the drive through lane, backing up until their tires hit the little concrete divider that separated the drive through lane from the rest of the lot. So about two feet of this car's trunk hung over into the drive through lane, making it impossible for anything bigger than a subcompact car to pull through past the menu sign to the window. This resulted in chaos as larger cars got stuck, unable to pull through, had to back out, setting off a chain reaction of backing out among subsequent customers.
The restaurant eventually shut down the drive through and posted an employee outside the restaurant (in freezing old temperatures) asking people to go inside and order. The poor staff apologized profusely and offered everyone free coffee or hot cocoa. They said they had no idea who the car belonged to, but suspected it was a guest at one of the adjacent motels. The staff had called a tow truck, but it was taking a while to get there.
Seriously, who does that?
ETA: Because of the placement of the window, the staff was not able to see who parked there or when they did it.
